The garbage -g u basket receptacle B is made of metal and is arches or rentrant portions in the under inthe form of an open work basket so as to also performy the double function of a strainer for the passage of juices and a grate for the escape of ashes. The bottom of said basket B is readily removable and as shown in Figs. 8 and 9, is formed continuous withV portions 'at the opposite ends of the basket andconsists of a plurality of parallel spaced metal strips 22 which are bent intermediate their ends into wave form so as to provide side of the bottom and pockets in the basket on opposite sides of the arched portions.

The strips 22 are joinedV together by trans` versely extending' strips 23 secured to` the strips 22 at the bends therein. rEhe strips `22 are also joined together at lthe upwardly extending ends of the sides by transversely extending strips 24 secured to the strips 22. Strengthening bands 25 and 26 extend around the outside of they body of the basket Y at the middle and top edge respectively. The end strips v221 are spaced apartand secured 'at' their upper ends to the band 26 u and at their lower ends to the band 25.

Referring to Figs. 4, 8 and 9, it will be seen that certain of the bottom strips 22 have hooks 27 at'their ends which are arranged to hook over the upper edge of the band 25 atk opposite ends of the basket, the hooksfitting in spacesbetween the strips 221 ofthe body of the basket. In .thisl way the bottom, in case it becomes burned out, may be readily detached from the body of the basket and replaced by anew bottom, kas the hooks 27 at the ends maybe readily sprung into place, firmly holding the bottomy in proper position. The bottom being ffree at itsA endsV and having bends intermediate thereof, may expand longitudinally as the temperature rises.

y The sidesof thebasket are made of spaced metalstrips 28 secured at their upper ends to the band 26 andr also secured to the band 25,. vThe strips 28 are out so that their lower ends lieon a curve conforming to the curvature of the bottom ofthe basket, andy these lower ends-are secured to side plates v29 which are shape'd'like the removable bottom of the basket and secured to the bands 25 lower end to form feet 32. The feet`32 are located below'the bottom ofthe basket so `thatthe'latter will be held vapart fromA a support on which the basket stands to drain the juicy contents thereof. The basket is also provided with a suitable handle 88, by which it may be lifted, carried, or properly adjusted into its operative position in the combustion chamber of the incinerator.

Referring to Figs. 1 and 10, it willbe seen that the bottom of the basket is supported at the tops of the middle loops or arches by the lower inturned end 281 of the side strip 28 opposite it. The inturned ends 281 (see Fig. 10) engage under the strips 28 at the top of the arch and strengthen the arch and support the removable bottom intermediate its ends.

1n making the basket I find that the parts can be very economically secured together by spot welding them, but of course any suitable or approved method of uniting the parts or making the basket may be einployed. A very satisfactory strong and light basket may be made of round wire spoty welded. Such a construction is preferable because owing to its skeleton-like formfit has the advantage that the juices more readily drain from the garbage and there is greater direct heat contact with the garbage or refuse and it is also cleaner and more sanitary.

The basket may also be formed of castings or made out of stamped sheet metal. 1n Fig. 5, l have illustrated a basket of the latter type; the bottom 34 being made of sheet metal with the openings 35 stamped therein. In this form I have shown only'one inwardly bent arch portion in the bottom but any number of arches and pockets can of course be provided, openings being stamped in the sides of the arches. The sides 36 are made of plates with openings 35 stamped therein and the lower edge thereof is shaped to conform to the curvature of the bottom. The bottom 34 and sides 36 are secured together at their edges and a band 8'? extends around the upper edge of the basket. 110 Handles 38 are secured to the ends of the basket and plates 39 provided with hooks 40 and feet 41 are secured to the basket as in the form shown in Fig. 4. v

The basketcontaining the refuse or gar- 115 bage is suspended in the lcasing 15 by means of the hooks 31 which engage in openings in the plates 42 secured to the opposite sides of the inner wall of the casing. When the basket is properly positioned in the casing, 120 the arched portions thereof extend over and opposite the burner pipes 43 which extend longitudinally of the arched portions. The burner pipes 43 areprovided with connections 44which extend throughthe openings 125 17 in the wall kof the casing. The burner pipes y43 are provided with rows of outlets 45 for fuel, and these outlets are located on opposite sides of the burner pipes, and since the burner pipes are located in the space 130 andfia-*meitherefrom"to entrthe basket through-at#resembleparesse Oropa i spaed bottom?

From theforegoing description it will `be seen that I have provided an extremely simple and efficient household incinerator whichhas many advantages over complicated expensive incinerators now. on the market. The parts of the incinerator are few in number, portable, designed to give long service and arranged so they may be readily and cheaply repaired or replaced when necessary.

Garbage refuse as it accumulates from the table, or otherwise, may be placed in the scrap basket receptacleA which may be set in the sink or any point convenient for filling. Nhen the receptacle is filled and the juices have somewhat drained oii', the hinged lid or door of the incinerator may be opened and the receptacle suspended on the supports in the incinerator casing, in an exact and proper position over the fuel burners, so that the fla-me from the burners may pass through the openings in the receptacle to the garbage. The lid or door is then closed, the `burners lare lighted and the draft is regulated. The flames from the burners shoot through the openings in the arched portions of the receptacle and the process of incineration is thus begun. In some cases, vwith garbage or refuse of a certain character the burners may be extinguished before incineration is complete, as the material will be sufliciently dried out to actas its own fuel. Garbage from the table is often so Y wet that it requires heat units other than its own for drying out or before its own heat units are available for incineration, and the present form of incinerator dries the garbage suiiiciently for its incineration. It is to be understood that they basket receptacle may be used in stoves which are suitably provided with a fuel supply such as gas flames or liquid fuel burners as well as air inlets and flue connections or outlets, and that f have means for properly supporting and receptacle having an inset partitioning por-H tion into which the jets from the burner `are directed, and the said casing having an opening through which the receptacle may bel bodily insertedl into or removed from the combustion chamber, as desired.
